Compared with 4G network, E2E radio network latency in 5G is reduced to 1 ms with peak data transfer rate of 20 Gbps; this offers an ultra-responsive connection with ultra-low latency [158].¹⁵ URLLC is expected to play a key role in a wide range of mission-critical and industrial automation applications such as remote medical assistant, autonomous vehicle control, and robot and drone control that rely on high data rates and low latency [159, 160]. One important aspect of URLLC scenarios is to communicate in real time or within a very short time. Consequently, applications that require highly reliable communication can be implemented in 5G, such as remote-controlled plants or smart factories. At the same time, 5G exploits lower frequency bands that propagate farther in the environment, providing a more robust means of communication between IoT devices in buildings. Such a feature also leads to prolonged devices battery life (about years).

In addition to highly reliable communications [161], 5G new radio introduces the concept of extra transmission redundancy to better support industrial applications in URLLC scenarios [162]. Design of URLLC services heavily relies on a number of factors including more reliable channel coding techniques, effective resource sharing (control-flow and data), and grant-free transmission for uplink data, all supported by 5G new radio standard [163].
